ORANGE COUNTY, Florida (WESH) — The couple involved in an in vitro fertilization mix-up case in Orange County has reached a custody agreement with the genetic parents, documents show.
Background A Florida couple, Steven Mills and Tiffany Score, filed an emergency lawsuit against an Orlando fertility clinic, alleging their newborn child was not genetically related to either of them after an IVF procedure.
The couple used their own egg and sperm to create three viable embryos at the clinic, Fertility Center of Orlando.
In March 2025, one of the embryos was implanted in Score, resulting in a successful full-term pregnancy. The couple’s healthy female child, Baby Doe, was born on Dec. 11, 2025.
The parents became suspicious when Baby Doe displayed physical characteristics of a child who was not racially Caucasian, despite both Mills and Score being Caucasian.
Months later, testing confirmed the genetic parents of their baby.
Custody agreement A new court filing shows the couple has reached a custody agreement with the genetic parents.
The filing also reveals that the birth parents will remain the girl’s permanent custodial parents.
The remaining embryo from the couple has been transported to a new clinic under the care of a new physician, with DNA verification expected in six weeks.
During a hearing held on Monday, concerns were raised about potential errors involving other patients at IVF Life.
“We may need to get more information from the clinic regarding that patient’s history as well as the rest of those in the same retrieval group, that patient 004 and our clients were in,” the couple’s attorney said.
Attorneys for IVF Life and clinic Dr. Milton McNichol did not provide updates during the hearing.
